sTEAM -MlJFFLER.

SPECIFICATION forming part of Letters Patent No. 239,023, dated March 22, 1881. Application filed October 1, 1880. (No model.)

To all whom it may concern Be it known that I, ALFRED BERNEY, a citizen of the United States, residing at Boston, inthe county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Steam-Mufflers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to steam-mufflers, and the object is to prevent the disagreeable noise caused by the escape of the steam from safetyvalves, and also to assist in heating the feed water.

The invention consists in connecting the safety-valve, having a hood, with a pipe leading to a tank in the tender, from which the steam finally escapes through a suitable muffler, all of which will be more fully described hereinafter, reference being had to the accompanyin g drawing, representing a longitudinal section of part of a locomotive-boiler and the tender.

A is the shell of the boiler, having furnace B, tubes 0, and steam-drum a. Preferably on top of the steam-drum is arranged a safety-valve, E, being covered with a close case, and to this is connected a pipe, F, which is provided with a suitable cock or valve, f.' This pipe F extends downward, and is connected by a flexible tube, 9, to the pipe G, extending through the tender,

and passes upward and is curved down into a er. At the lower end this pipe is provided tank, either separate or connected to the tendwith a rose-head, b, or perforated branch pipe. The tankis closed on top and is provided with any suitable steam-muftler, I, through which any uncondensed steam is allowed to escape. A pipe-connection, t, is arranged between the pipe .G and muffler I, and is provided with a cook or valve, it, which, when opened, allows the steam to escape directly into the muffler, if desired.

The operation is as follows: When the steam escapes from the safety-valve it passes through the pipes F and G into the tank on the tender, and will assist in heating the water therein, and any steam not condensed will escape through a muffler of any kind.

If desired, the steam can be allowed to escape into the air by closing the valve f when it is found that the water in the tender becomes too hot.

I am aware that the steam from safetyvalves has been employed to heat the feedwater, and it has also been sought to suppress the noise by this means; but it has been found that this cannot be successfully accomplished except by overheating the water and causing ebullitions in the water and stirring up the sediment.

A pipe from the cover of the safety-valve, leading into a small tank of water set into the feed-water tank, having an outlet for the escape of the steam not condensed can be used without any muftler, the purpose of the extra tank being to regulate the heat, 850.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is'

1. In a steam-muffling apparatus, the combination of a safety-valve and pipes extending into the tender with a closed tank provided with a suitable muffler, substantially as specified.

2. The combination of a safety -valve, E,

having closed case, with a pipe, F, provided with cook], the flexible tube 9, and pipe G, extending into a closed tank, H, having steammuffler I, all arranged substantially as described.

3. The combination of ,a safety-valve, E, pipes F and G, extending into a closed tank, H, having steam-muffler I, with a pipe, t',1novided with cock h, all arranged substantially as set forth.

4. The combination of a safety-valve, E, pipe G, extending into a tank, H, inclosed in tank D, and pipe 0, substantiallyas specified, and for the purposes set forth.

. In testimony whereof I affix my signature in presence of two witnesses.
